Exactly mate... Exactly... I'd rather have the mount with good optics for $20k total than the mount with an RCOS for 45~50k..
Ps. AP1200, Easily portable.. splits into two parts, each section is less than 20kgs.... wack it on the AP 38" portable pier and you're a go!

The cost difference between the 900GTO and the 1200GTO is only a few grand, and its nearly double the payload capacity.. Do you know how many DSLR + ED80 setups you could run on an AP1200 at once!

haha!! I reckon about 20 + 1x ST80 +QHY5 for guiding... That way, you could capture 20x20min subs in 20 minutes.. Think about it!!! Efficiency!! 6hrs 40min data captured in 20 minutes.. Awesome!
Like I said - Dare to dream..
